2005 TrailBlazer issue
I got a call from the wife that the TB was dead and wouldn't start. When I got there I found it dead, could not change gear positions, and I was unable to put the key in the *remove* position. Thinking that the TB'* neutral switch was out of line, I rocked the truck back and forth to no avail. I had no lights, door locks. All doors we're unlocked except the rear. Remote opener didn't work either. I jumped it, it started right up, and has started and operated fine ever since. Prior to the jumping I touched cables to confirm connection and got spark. Any of this sound familiar to anyone? What could cause it? Thanks.
